A neutral water molecule (H(2)O) in its ...

A neutral water molecule `(H_(2)O)` in its vapour state has an electric dipole moment of magnitudes `6.4xx10^(-30)C-m`. How far apart are the molecules centres of positive and negative charge?

A

4 m

B

4 mm

C

`4 mum`

D

`4"pm"`

Text Solution

Verified by Experts

The correct Answer is:
D
`P=q(2a)implies 2a =(6.4 xx10^(-30))/(10e)`
`= (6.4 xx10^(-30))/(10 xx1.6 xx10^(-19))= 4 xx10^(-12) m = 4` pm
